IMPROVEMENT IN PLOW POINTS AND SHARES.

Specification forming part of Letters Patent No- 154.139, dated August18, 1874; application filed November 2'2, 1873.

To all whom it may concern:

Be it known that I, J osEPH F. HERRING, of Mansfield, in the county ofRichland and State of Ohio, have invented certain new and usefulImprovements in Plow Points and Shares; and that the following is afull, clear, and exact specification thereof, which will enable othersskilled in the art to make and use the'said invention.

My invention consists of an improved plow point and share, made of onepiece of metal,

and constructed, substantially as described hereinafter, with clasps andsocket, so as to be securely clasped or wedged into ,place on themold-board of the plow, without the use of rivets, bolts, or screws.

In the drawing, which shows a bottom perspective view of my improvement,A is the point; B, the socket; G, the cutting-edge of the share; D D,the clasps. The point of the moldboard is thrust into socket B, andbeneath the overlapping edges of clasps D D. Both socket B and clasps DD are flared, so that the edge and side of the mold-board act likeWedges, tending to force the attached point and share more firmly intoplace as the plow is used.

When dull, my point and share can be easily knocked off by a few sharptaps from behind, especially if first slightly heated. They can then besharpened,and when worn out a new one can quickly be set in its place.

My point and share are made of one piece of metal, with the exception ofthe clasps. These clasps D D may be either riveted or welded into placeon the share, or secured by any other suitable or well-known means, suchas screwing or bolting. I prefer riveting.

My point and share may be shrunk on the mold-board by being slightlyheated before being wedged on. This expands the metal, and when it hascooled it is very rigid.

What I claim as my invention isr The combined plow point and shareherein described, consisting of a single steel plate, A 0, having thepoint-socket A B, formed at its front end to receive and cover theplowpoint, and provided with the clasps D D to hook under the front edgeof the mold-board, substantially as and for the purpose specified.
